FIREPLACE.

Specification of Letters Patent No. 32,283, dated May 14, 1861.

To all whom it may concern:

Be it known that we, JOHN S. GAUsoN and CHARLES T. Corr, of the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Fireplaces and Air-Chambers in Connection Therewith; and we do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.

The nature of our invention relates, 1st, to the peculiar construction and configuration of the fire back as hereinafter set forth. 2d. I11 the construction of a jacket made of tin or other material of good heat reflecting qualities and used in combination with said fire back for the purposes herein described. 3d. In the relative arrangement of air chambers as described. 4th. In the construction and arrangement of a crescent or other fire chamber in combination with a recess in the fire chamber.

Figure I is a front elevation of our improved fire place. Fig. II is a vertical section of same. Fig. III is a cross section.

Letters of like name and kind refer to like parts in each of the figures. a

A is the fire chamber, which from the pe culiar construction of the fire back is higher and more concave than in common fire places. a

B represents the fire back which we make of cast iron. It is so constructedas to extend upward and above the mouth ofthe chimney, and then downward and forward as represented at b, so as to form the recess D, above the mouth of the chimney. It then makes a semicircular bend as shown at If, and then recedes again upwardly, as representedat'b so as to form the top and bottom of the air chamber 0. This part 6 projects far enough over the side plates F and back plate to form a top or cover to the air chambers as shown by the dotted lines in Fig. I. This fire back may be cast in one piece'as a whole, or it may be cast in two or more parts and then properly put together when the fire back is set .into the chimney for use.

F represents side plates made of cast iron and used in connection with the fire back and form the side jambs of the fire place.

G, is the front plate also made of cast iron. Openings h are made through this plate the air chamber 0.

near the bottom which connect with the air passages formed by the horizontal partitions z' for the purpose of conducting the cold air from the lower parts of the room into the air chamber 0. This plate is made curvilinear or with anoutward swell, so as to afford space for the ingress of the cold air at h, and the egress ofthe heated air at k, a passage or chamber being also formed in rear of the top part of this plate and over the fire place as shown at. J This chamber or passageway communicates with the air chambers 0, so

that there is a connection and communication between all of the air chambers.

L is a crescent or other shapedtube or air chamber placed horizontally across the fire chamber and secured to the side plates F, a short distance from the fire back and below It opens into the side air chambers 0 It adds to the heating capacity of the air chambers and insures a more perfect collection and combustion of the smoke and gases in the recess D. p E represents the brick work of the chimneyour improved fire place being placed therein; M, fire grate.

N represents a jacket made of tin or other polished metal having good heat reflecting qualities. It is, placed in rear of the fire .back and side plates and is connected therewith as shown at i N for the purpose of combining with the fire back to form the air chambers in the rear at the sides and over the fire chambers as represented. The smooth and polished surface of this jacket being a poor radiator, of heat but possessing good reflecting properties it will reflect the heat back into the chamber and prevent it from passing through. to be absorbed by the brick work. All (or nearly all) of the heat will therefore be retained within the chamber for heating the air therein which passes out through the, appropriate openings is into the room.

The fire back when constructed as herein described and properly set in the chimney gives the proper form to the mouth and throat of the chimney so as to insure the proper draft. 4th. It forms atop or cover to the air chambers c and 0 as described. 5th. In combination with the jacket N it is an essential device for the formation of the air chambers c 0 and 0 A fire place constructed (with air chambers) as herein described is ornamental, cheap, durable and'may be put into old as well as new buildings and answers all the purposes desired.

The cold air from the lower parts of the room passes through the openings h into the passage way formed by the horizontal partitions z and is thence conducted into the chambers c, c, 0 where it becomes heated, and thence into the chamber or passage J, and through the openings K into the room. We thus secure all the heatwhich is conducted through the fire back and side plates for heating the air in the chambers; which heat is distributed through the room by the circulation of the air, as described. lVe also secure all the advantages of radiated and reflected heat which can possibly accrue from fire places of the. best ordinary con struction, and the combined advantages of fire place and furnace. The fuel (coal or wood) burns clear and bright, the smoke and gases rise into the recess D, and are consumed, a complete combustion of the fuel is obtained, all the heat therefrom is saved for warming purposes and a uniform and healthful temperature is produced in the room.

We claim- 1. So constructing the fire back B, as that it will extend upward and above the mouth of the chimney and then downward and forward as shown at b with semicircular bend b receding again upwardly as shown at b for the purposes and substantially as herein described.

2. Said fire back being constructed substantially as described, we claim in combination and arrangement therewith, the jacket N, for the purposes set forth.

3. The combination of the tube or air chamber L with the recess D as and for the purposes set forth.
